Thanks for posting. It was interesting, but I didn't like the way they presented it as if each new shaving product was some "improvement" in technology. The fact is that almost every "innovation" after the DE razor was purely to make the product cheaper or easier to learn. And I would argue that after the basic disposable, every new "innovation" was a pure gimmick. Especially the way the big name companies just keep adding more razors to the cartridge heads, adding "strips" and "bars" and all sorts of weird crap to the cartridge head, and now adding batteries so the whole convoluted mess vibrates. It's pure gimmickry. NOT progress. The best shave is still the old fashioned wet shave with a nice, thick brush lather made from a quality English soap or cream.
